Exception on text selection in web environment with particular pdf

[Pietro Beccegato]

I've implemented sfPdfViewer and works fine, except with some particular pdf produced by a converter from PCL5 to PDF that comes from AS400 environment.

Trying to select text from some of these pdf, in debug I get this error:

════════ Exception caught by gesture library ═══════════════════════════════════The following IndexError was thrown while dispatching a pointer event:RangeError (index): Index out of range: no indices are valid: 0
When the exception was thrown, this was the stackdart-sdk/lib/_internal/js_dev_runtime/private/ddc_runtime/errors.dart 236:49 throw_dart-sdk/lib/_internal/js_dev_runtime/private/js_array.dart 581:7 _get]packages/syncfusion_flutter_pdf/src/pdf/implementation/exporting/pdf_text_extractor/image_renderer.dart 658:40 [_renderTextElementWithLeading]packages/syncfusion_flutter_pdf/src/pdf/implementation/exporting/pdf_text_extractor/image_renderer.dart 327:17 [_renderAsImage]packages/syncfusion_flutter_pdf/src/pdf/implementation/exporting/pdf_text_extractor/pdf_text_extractor.dart 279:13 [_getTextLine]...Event: PointerHoverEvent#48320(position: Offset(1366.7, 326.6))    position: Offset(1366.7, 326.6)Target: RenderMouseRegion#79d36 relayoutBoundary=up6    parentData: <none> (can use size)    constraints: BoxConstraints(unconstrained)    size: Size(593.3, 541.3)    listeners: hover    cursor: SystemMouseCursor(basic)════════════════════════════════════════════════════════════════════════════════

The text does not be selected and when the issue is in webapp (not debug) the web app is freezed, because the "Index out of range..." error is reiterated many times.

As attachment, there's one of these pdf that produce the error.
